Question

Use the real number line to find the range of values of x for which:

x < 0 and –3 ≤ x < 1

Answer 1

x < 0 and –3 ≤ x < 1

Both the given in equations are true in the range where their graphs on the real number lines overlap.

The graphs of the given in equations can be drawn as:

x < 0

–3 ≤ x < 1

From both graphs, it is clear that their common range is –3 ≤ x < 0
